Can I avoid mobile network tracking on a Privacy Phone?
Not while the phone is on the mobile network. Carrier tracking on a privacy phone in Australia continues while the SIM is active: the network still sees the handset identity and which tower it is using.
Telstra, Optus, Vodafone and the networks that resell them see the handset through the SIM. They see the IMEI (the unique handset identity) and which tower you are on, and they keep call and message records. In a city that location is often tens of metres. In the bush it’s much wider. Australian law requires them to keep specified metadata for at least two years. GrapheneOS does not write that away.
What a Privacy Phone changes about mobile tracking
GrapheneOS does not require a Google or Apple account.
The operating system no longer reports home to Google or Apple.
Carrier apps are not pre-installed.
You can control network, sensor and location access per app.
Profiles let you separate work, family or sensitive use.
A GrapheneOS privacy phone does not stop network-level carrier tracking.
What Telstra, Optus and Vodafone still see
While the mobile radio is on with a SIM, the carrier sees the registered service, the handset identity (IMEI) and the cell tower the phone is using. GrapheneOS cannot hide these from the carrier. The same applies to networks that resell Telstra, Optus or Vodafone.
Tools that limit mobile network tracking
Tool
What it does
Airplane Mode
Radios off. Turn Wi-Fi back on for data if you want.
LTE-Only (4G) Mode
4G/VoLTE for calls. Smaller radio surface than 5G.
Network tile
Apps lose the internet until you allow it (kill switches)
Proton VPN
Hides your IP from the sites you visit.
MAC Randomisation
New Wi-Fi and Bluetooth names each connection.
Tracker Tools
Pro Bundle tools for detection of trackers (tracking)
Faraday bag
No radio in or out while sealed. Included with Pro Bundle.
How people actually use this
At home on Wi-Fi and VoIP when they do not need a mobile number.
On the road with a normal number for calls, SMS and banking.
In silence with airplane mode or a sealed Faraday bag when they want no network contact.
For messages without towers, using Off-Grid devices (no SIM, no towers, no tracking).
Common questions about mobile network tracking
Does a VPN hide me from Telstra?
No. It hides your IP from the website. The carrier still sees that the handset is on their network, and still keeps the metadata the law requires.
What is metadata retention in Australia?
Carriers and relevant providers must keep specified telecommunications metadata for at least two years under the Telecommunications (Interception and Access) Act 1979. This includes subscriber and device identifiers, source, destination, date, time, duration, type of service, and location of equipment (such as cell towers). It does not require retention of message content or full internet browsing history.
Can police track my phone in Australia?
Agencies can lawfully seek telecommunications data under the TIA Act with the required authorisations. This is not the same as a consumer “track my phone” button. The data that can be requested includes the metadata carriers are required to retain.
Does airplane mode stop carrier metadata?
Airplane mode stops new cellular contact while the radio is off. It does not erase metadata the carrier already holds.
What about IMEI tracking?
The IMEI identifies the handset to the network. While the phone is connected, the carrier already sees the IMEI. IMEI blocking (used for lost or stolen phones) stops the handset working on Australian networks; it does not locate the phone.
Does a Faraday bag stop phone tracking?
A sealed Faraday bag blocks radio in and out, including cellular, and typically Wi-Fi, Bluetooth and GPS reception while sealed. It does not delete past carrier records.
Is off-grid a phone number?
No. Off-grid mesh devices send messages between radios without a SIM or towers. They are not a phone number.
A GrapheneOS privacy phone reduces the tracking that happens on the device itself. When you need no SIM and no towers, consider off-grid private communications.
